Existence itself is observer-dependent. Nothing exists if there's no observer. This is not philosophy; it's pure science. Almost Everything is made of the canvas on which the Universe happens, which is absolute Nothing; Void; no space, no time, no matter. These 3 things only exist inside the ripple effect which forms the universe, forming instantly and endlessly on the canvas of void. As such, as far as the canvas is concerned, where there's no observer, there's nothing to observe. Nothing ever happened (in the same way there's only the surface of the pond, there's only water, the ripple effect happening on the surface is effectively nothing). However, inside any of the endless ripples, there's time, there's matter, and there's space. There's a universe to observe by observers inside the universe, or even - one day - from one ripple to the other. The neutron, like black holes, and like the "space" between ripples, is all the same. There's no observer. There's nothing to observe. Time, space and mater do not exist.
